Uncut lab-grown diamonds have no cutting or polishing process. They keep their original shape and appearance, which depend on the production method.
CVD diamonds have a more irregular and flat shape. HPHT diamonds have a more octahedral or cubic shape.
Uncut lab-grown diamonds find diverse applications beyond traditional jewelry based on their quality, size, and shape. From industrial uses, such as abrasives, cutting tools, drill bits, and heat sinks, to innovative technologies, these diamonds play a crucial role in various sectors. We delve into the wide array of applications that make uncut lab-grown diamonds versatile and sustainable.
Some uncut lab-grown diamonds that serve industrial purposes are low-quality, small, and irregular, and unsuitable for jewelry.
Some uncut lab-grown diamonds are high-quality, large, and well-formed, and serve jewelry or investment purposes. These diamonds are rare and valuable, and sell as rough diamonds or cut and polish into finished diamonds.
Some people like uncut lab-grown diamonds for their natural and raw beauty. Others like cut and polished lab-grown diamonds for their brilliance and fire.
Here is a table comparing key attributes of Uncut Natural Diamonds and Lab-Grown Diamonds:
Uncut Natural Diamonds
Mined from the Earth
Manufactured in controlled lab environments
Variable, depends on individual stone
More consistent quality within production batch
Random mineral impurities
Controlled levels of nitrogen impurities
Full range of fancy colors found
Mainly colorless and near colorless grades
Wide range, affected by natural imperfections
High clarity, fewer visible inclusions
Limited by scarce large natural rough diamonds
Available reliably in +10 carat sizes
GIA, IGI certification for 4Cs
IGI lab-grown certificates
Approximately ~$4,000 to over $50,000 per carat
40-50% discount compared to equivalent natural diamond
Risks associated around some mining operations
Guaranteed conflict-free sources
Natural diamonds are scarce and expensive, limited by the market supply and demand. They also involve ethical and environmental issues, such as conflict, mining, and trade. Lab-grown diamonds are abundant and affordable, not limited by the natural resources and produce on demand. They also avoid violence, exploitation, or pollution.
